When the opposite radial arms 0 the frames 17, 18 move in a directionitoward the flanges 22 the gradually release their pressure on-the c ains 27 and the springs 32, at suchtimes, move the slides 25 outwardly on the sleeves 26 and keep all slack out of the chains, holding the latter taut. The sleeves 26 are provided withs'paced lines or graduations, as shown in Figs. 2 and 3, along which the outer edge of the slides 25 move and which may be used to-v denote pounds or horse-power.

In the drawings I illustrate a pulley-wheel '16 having two sets of dynamometer devices,

one at each side thereof and cooperating therewith, and one set of'said devices being shown in Fig.1, while that at the other side of the pulleyawheel is shown in Fig. 2 and com rises the frame 18 with its radial arms 20, 's ide 25, sleeve 26, spring 32 and chains 27, the latter passing over the pulley-wheels 29, 30 carried by the said arms and secured at their outer ends to the flanges 22 of the wheel 16. It is to be understood, however, that I do not limit the invention to the duplication of the dynamometer devices at op posite sides of the wheel 16, sincezmy invention is fully embodied in each set of said devices. The 5 rings 32 are light springs and only exert su cient power to move the slides 25 outwardly and-kee the chains 27 taut.

The ulley and sha t shown in Figs. 1 and 2 may e operated in either of two ways, the dynamometer devices making the proper indications under either method of operation.

I ower applied to it and transmit motion to t wheel 16 from which, by means of a belt, power may be transmitted to the machinery to be driven; or power may be applied to the pulley and transmitted by it to t e shaft 15, whence through any suitable or usual connections said power may be transmitted to the machinery to be driven.

If power should be applied to the shaft 15, the pulley-wheel 16 being free thereon, the frames 17, 18 being fast to the shaft will be turned in a direction from the flanges 22 of the wheel 16, as shown in Fig. 1, and partly compress the springs 23 (due to the movement of the rods 21) against said flanges, and thereupon after the springs 23 have been sufficiently compresse to overcome the ine pulley-- edges of the slides 25. The position of the slides 25 will vary with the distancethe ends of the radial arms of the frames 17, 18 may be from the flanges 22 of the wheel 16, and the position of said arms with relation to said flanges will vary with the resistance offered by the work to the wheel 16, the greater the resistance of the work the wider the space will be between the outer ends of the arms of the frames 17,18 and the flanges 22. The movement of the frames 17, 18 from the flanges 22 creates a pull on the chains 27 and slides 25, the latter thereby being drawn inwardly along the sleeves 26 and denoting by their position along the graduations on said sleeves the amount of power consumed.

. If the power were applied to the wheel 16 to be by it transmitted to the shaft 15 and thence from said shaft. to whatever it may be desired to operate, said wheel would be rotated in a direction to carry its flanges 22 from the outer ends of the radial arms of the frames 17 18 and a ainst the springs 23, and after the springs 23Tiad under such condition become sufliciently com resscd to overcome the inertia of the work, t e frames 17, 18 and shaft 15 would start in motion and thereafter continue to rotate so long as adequate. power remained on the'wheel 1 6. The movement of the flanges 22 in a direction from the outer ends of the arms of the frames 17, 18 results in a pull being exerted on the chains 27 and the inward movement of the slides 25, the same as occurred in the illustration above explained in which the Ipower instead of being applied to the whee 16 was first applied to the shaft -15 and-transmitted to said wheel.

The eneral purposes of dynamometers are welF elaborate explanation. The resent dynamometer is eflieientfor all of the purposes for which rotative 'dynamometers are employed. For illustration, the engineer of a factory by observing the position of the slides 25 along the graduations of the sleeves 26 may determine therefrom whether conditions in the factory are normal or otherwise. The e ineer would know in advance just about t e amount of power required for the factory, and if by looking at the graduations he should see that an excess of ower is being consumed, he would be led to find the cause of this condition, which might be due to a understood and hence require no shaft getting out of line or by a hot-bearing or by some obstruction in some part of the machinery. If the graduations indicated a consumption of less than the normal amount of power required for the work, the engineer would endeavor toascertain what had happened to put the plant out of normal running condition, which might be caused by either a belt slipping or having become broken or by other event.

The invention is also useful plants where power is sold, and the wheel 16 may be connected with the main line or prlmary shaft from which the power is transmittedto the several consumers. The friction due to the running of this main line or primary shaft might consume one horse-power, and

under such condition when the said shaft is in motion, without any transmitting means from the same being connected therewith, theslides 25 would move on the sleeves '26 one space and indicate the consumption of the one horse-power. Now if a customer should require six horse-power, his belt'will be connected onto the main line or primary shaft and this increased load on. the wheel 16 means for giving off power.

. other shaft giving off power.

will result in the slides 25 being moved inwardly six spaces if such customer were actually using only six horse-power. If the customer should be using eight horse-power instead of the six for which he was'paying, the excess would be. denoted by the position attained by the slides 25, and if he were consuming less than six horse-power that fact-would also be indicated by theposition of the slides 25. As many transmission belts as there may be customers may be connected with the main line or primary shaft, and if the first customer were consuming six horse-power and the slides 25 had moved to the seventh space on the sleeves 26, and the second customer desired four horse-power and obtained the same and used no greater amount, the slides 25 would then move inwardly four more spaces, indicating that both the first and second customers were consuming only the total amount of power paid for. v "1 In Figs. 6 .to 9 inclusive I illustrate my invention as embodied in a coupling comprising matching members or sections 40, '41 keyed on the respective adjoining ends of shafts 42, 43, one of which maybe connected with "a source of power and the other with For illustration, the shaft 42 may re resent-an engine shaft, or water-wheel sha t, or other shaft operated by power, and the shaft 43 may represent a dynamo-shaft, a line shaft, or The member or section 40 of the coupling is keyed upon the end of the shaft 42 and the extreme end portion of the latter preferably projects into ut is not keyed with the hub of the coupling member or section 41, as shown in Fig. 7.

shaft 43, and the sections 40, 41 .are close together and each is composed of a hub,

radial arms, and a rim. On the shaft 42 is freely mounted a sleeve 44 corresponding with the sleeve 26 shown in Fig. 3 and upon this sleeve 44 is mounteda slide 45 to indicate by its position on the sleeve 44 the amount of power being consumed. The slide 45 is normally pressed outwardly on the sleeve 44 by means'of light spiral springs 46 inter osed between the'same and a flange 47 on t e inner end of the sleeve 44. The slide 45 is connected by chains 48 with flanges 49 of the coupling section 41, saidchains extending from the slide 45 through the springs 46 and thence over pulley wheels 50 and thence passing in opposite directions parallel with the face of the cou ling section 40 to pulle wheels 51 'carrie by flanges 52 integral with the coupling section 40, whence said chains pass over said pulley wheels 51 and are fastened at their'ends to the afore said flanges, 49 integral with the coupling section 41. When the sections 40, 41 of the coupling are assembled, as shown in Fig. 7, the flan s 52, 49 thereof match and pass'into line with one another. Each of the flanges 52, 49 is formed with four apertures 53 and in these apertures of the flanges 52 are secured curved rods 54, corresponding with the rods 21 shown in Fig. 1, said rods 54 passing from the flanges 52 freely through the apertures53 of the flanges 49 and being provided beyond said flanges 49 with coiled springs 55, which correspond with the springs 23 in Fig. 1.

When power isapplied to the shaft 42 it will'set in motion the coupling section 40, and this section will move its flan cs 52 in a direction from the flanges 49 of t e section 40 until the s rings 55 have attained the proper degree 0 compression, and thereupon the coupling section 41 will follow with and be rotated by the coupling section 40 and transmit its power to the shaft 43. The movement of the flanges 52 of the coupling section 40 in a direction from the flanges 49 of the coupling section 41, results in the pulley wheels 51 drawing on the chains 48 and effecting the inward movement of the slide 45 on the graduated sleeve 44, the position of said slide on said sleeve being governed by the relation of the flang'es52 to the flanges 49. The dynamometer devices presented in Figs. 6 to 9 inclusive operate on identically the same principle as that described with res set to the devices shown in Figs. 1 to 5 inc usive and may, if desired, be used for identically the same purposes described for the construction shown in Figs. 1 to 5 inclusive, in which event the shaft 43 of Fig. 7 would re resent the main line or primary spa? am the shaft 42 an engine or motor s a t.
